Adidas Terrex Agravic Speed 2 review: a featherweight racer for technical trails
The lightest Agravic yet pairs a lively dual-layer Lightstrike (standard and Pro) ride with serious Continental grip. It's brilliant, if you're the right runner for it.
Adidas Terrex has been on a roll lately, and the Agravic Speed 2 is the sharpest tool in the lineup for specialist trail runners.
This is the lightest, sleekest shoe in the Agravic family; a non-plated technical trail racer built for up-tempo efforts and racing over moderate to sub-ultra distances, where agility, ground feel, and precise foot placement matter more than maximal protection.
It sits below the higher-stacked, plated Agravic Speed Ultra 2 in the range. Less shoe, more connection, more speed for shorter and mid-length efforts.
I have been running in the Adidas Terrex Agravic Speed 2 on my local trails, and I love almost everything about it. Here's my full take, including the two important things you need to know before you buy.

Sizing and fit
The Agravic Speed 2 fits true to size on a streamlined, low-volume race last, so this is a snug shoe by design and not one for wide or high-volume feet.
The midfoot and heel lockdown is excellent once dialed in, helped by that slingshot-style rear hold, and I get zero heel movement even on steep descents.
The one fit note; the chamfered toe box tapers enough that it feels a little snug against my little toe, something I noticed most toward the end of runs.
Performance review
This is where the Agravic Speed 2 makes its case, and where you find out whether it's your kind of shoe, or not.
A nimble, responsive ride that begs you to push on
The dual-layer midsole is the heart of it: soft, high-rebound Lightstrike Pro underneath for energy return and propulsion, with a firmer Lightstrike layer on top for some composure and protection.
There's no plate here, and the shoe is better for it; most trail shoes are...
The ride stays naturally flexible with real ground feel, while the moderate rocker (a noticeable heel bevel into an early forefoot roll) keeps transitions smooth without forcing your stride.
The result is a nimble, lively, fast ride that encourages a higher cadence, and it makes runnable singletrack, gravel, and moderately technical ground genuinely fun.
It has that same Lightstrike Pro spark I praised in the Adidas Terrex Agravic SL, distilled into a much lighter, racier package.

The bouncy EVO SL magic finally comes to the trail, wrapped in grippy Continental rubber and a stable ride, for a very fair $160.

Cushioning is adequate and reactive for the stack rather than plush. It feels connected and efficient, which is exactly what I want from a shoe like this.
Continental grip you can trust almost everywhere
The Continental rubber outsole with its 3-4mm multi-directional lugs delivers excellent, versatile grip for the lug depth.
It bites confidently on dry hardpack, rock, loose gravel, and mixed surfaces, and it stays reliable in many wet and moderately muddy conditions too.
It even handles road-to-trail transitions cleanly, though if hybrid running is your priority you'll be better served by my best road-to-trail running shoes picks that have a bit more protection underfoot.
The honest limit is slick wood/rock, and deep, sticky mud; self-cleaning will be ok but the shallow profile can only do so much there.
Rubber durability has been strong, which I have come to expect from Continental outsoles.
Lockdown and breathability built for race day
The semi-transparent mono mesh upper is minimal in the best way, and ventilation is very good, as you would expect. My feet stay cool even at higher efforts in warm conditions.
Combined with that excellent midfoot and heel lock, the whole package disappears on foot once you're moving. Seamless TPU overlays add structure exactly where it's needed without adding weight.
This is a race-day upper through and through: light, breathable, secure, and honest about its priorities.
The narrow heel demands strong trail legs
Here's the most important thing to know before you buy: the platform narrows significantly under the midfoot and especially the heel.
On steep, off-camber, or rough terrain, that narrow heel introduces inherent instability if you haven't built strong trail running ankles and feet from running technical ground regularly.
As an extreme analogy, think of dropping onto a rough descent wearing ice skates; if your stabilizers aren't trained for it, the shoe won't save you.
Protection is minimal too; there's no rock plate, so sharp rocks make themselves known, and that ground feel is a feature for experienced technical runners and a liability for everyone else.
For comparison, it's worth noting the midfoot here is wider than the extremely narrow platform on the Speed Ultra 2 (but the heel is narrower), so to some degree the Speed 2 could actually be considered the more stable and trustworthy of the two on genuinely technical trails, so long as you don't heel strike.
If you want maximum security on technical ground, the Salomon S/Lab Genesis 2 remains my benchmark.

A specialist for fast, sub-ultra technical racing
Put it all together and the Agravic Speed 2 is a great minimal technical racer for advanced runners who love skyrunning-style trail runs.
Its sweet spot is fast efforts on mixed singletrack, moderately technical trails, and short to mid-distance racing, roughly up to the 25-50km range depending on terrain and how much cushion you need. Some runners will push it further on smoother courses.
It rewards neutral mechanics, good form, and real experience on technical ground.
That's the runner this shoe was built for, and for that runner it's one of the fastest non-plated options out there; you can see how it stacks up against the field in my best trail racing shoes roundup.

My verdict
I love the Agravic Speed 2. The ride is nimble, responsive, and flat-out fun, the Continental grip is outstanding for the lug depth, the lockdown is excellent, and the breathability is superb.
At $165 with no plate required, it's strong value for a shoe this fast and this light.
The two caveats are real, but they define the audience rather than undermine the shoe. The chamfered toe box runs snug at the little toe, and the narrow heel asks for strong, technical-trail-trained legs.
If that's you, this is a precise, high-enjoyment racing tool that deserves a place in your rotation.
Who should skip it: beginners, heavy heel strikers who need a stable platform, anyone racing ultra distances that demand more protection and cushion, and runners with wide or high-volume feet. If you want a more forgiving all-rounder from the same family, the Agravic SL is the one to look at instead.
